Patent CA-2390847-A1 (CA)
Title: Reel for supporting composite coiled tubing
Inventor: ISENNOCK CLINT W
IPC: B65H75/34
Filed: 2000-11-16
Abstract: This invention relates to two apparatus and one method for use in spooling composite coiled tubing onto a coiled tubing reel (10). One apparatus includes the modification of tubing reel cores currently in common use by the direct adhesion of a compliant material (22) to the hub (20). Another apparatus modifies the commonly used tubing reel hub by affixing several panels (26) concentric to the hub and mounted on compression springs (24).  The method entails the pressurization of the composite coiled tubing prior to spooling onto the tubing reel, and subsequently releasing the pressure within the composite tubing after it has been spooled onto the tubing reel. Both apparatus and the method protect the reel core by absorbing or eliminating the radially inward forces of the composite tubing resulting from the pressurization and corresponding contraction in length of the spooled composite coiled tubing.

Title: All optical clock recovery
Inventor: WHITE JOHN KENTON
IPC: H01S5/065
Filed: 2002-07-05
Abstract: All optical clock recovery includes a transmitter for generating an optical timing signal. The transmitter includes a semiconductor laser for the production of a dynamically synchronizable timing signal, the laser having an external resonator for feedback of the timing signal to the laser, the feedback having a delay time greater than a relaxation oscillation time for the laser, and the laser outputting an optical timing signal having a characteristic dynamic. The transmitter supplies the optical timing signal to a receiver configured to receive the timing signal and to synchronize to the laser on receipt of the timing signal, such that the receiver outputs a recovered timing signal having the characteristic dynamic. A number of receivers may be provided in sequence along an optical path, each receiver configured to receive the timing signal originally outputted with the characteristic dynamic from the transmitter, and synchronized to the transmitter on receiving the signal and thereby outputting a recovered timing signal having the characteristic dynamic. All optical clock recovery is provided without increased electronic complexity and avoids thermal drift.

Filed: 2002-07-15
Abstract: A three dimensionally structured laminate with high liquid absorbency of at least 5 g of liquid per g of laminate is disclosed which includes elevations and depressions which regularly occur and alternate relative to the plane of the laminate. The laminate includes at least one nonwoven layer and a shrunken web connected therewith. The connection between the nonwoven and the shrunken web is thereby achieved by hot melt bonding and the hot melt bonding is in the form of regularly positioned lines extending at least perpendicular to the direction of the strongest shrinkage of the shrunken web. Furthermore, spaces are formed between the nonwoven layer and the shrunken web at the alternatingly occurring elevations and depressions, which spaces promote the liquid absorption of the laminate. The laminates in accordance with the invention can be used especially as wiper cloth, wet wipe cloth or as a liquid dispenser for the cleaning or for application of liquids.

Patent CA-2396977-A1 (CA)
Inventor: DOUSTALY MICHEL
IPC: E03D9/08
Filed: 2001-01-10
Abstract: The invention concerns a sanitary appliance that is bonded to a toilet bowl and that delivers a low pressure water jet inside the bowl. The appliance makes it possible for the user to use the toilet privately under optimal hygiene and comfort conditions. The device consists of a valve with a moving head in which the pouring spouts (2, 11) move in the horizontal interstitial space between the toilet bowl porcelain and the hole-toilet seat assembly. The device also has a water supply connection (Fig. 5) consisting of a tube which is positioned in replacement of one of the two securing pins of the flush tank on the bowl. Opening and closing of the water directly depend upon the position of the pouring spouts (Fig. 6) actuated by the user. Water flows when the spouts face inward toward the bowl. Water stops flowing when the spouts are rotated and face outward. The appliance can be mounted on all toilets having a back flush tank.

Title: Automatic x-ray detection for intra-oral dental x-ray imaging apparatus
Inventor: VENTURINO GIANFRANCO
IPC: H04N5/361
Filed: 2001-01-04
Abstract: An apparatus and method used in intra-oral dental x-ray imaging equipment provides automatic detection of the x-ray emission in order to obtain timely transition to the image integration and acquisition phase with high level of rejection of false triggering induced by blemish defects of the image sensor or by variations of the ambient and temperature conditions. A solid state imager, such as a CCD image sensor, is continually clocked during the standby phase prior to irradiation from an x-ray source, so providing on the same time an output signal proportional to the accumulated dark current and the continuous removal of the same. A control unit analyses the output signal of the imager, detects the variation caused by the start of the x-ray emission using appropriate threshold levels, and automatically triggers the imager to the image integration and acquisition phases. Based on memorised maps of the imager blemish defects, and continually monitored variations of the imager output signal, the control unit will reject false triggering due to imager defects or variations of the ambient and temperature conditions.

Inventor: LAVI GILAD
IPC: A61M5/178
Filed: 2001-03-28
Abstract: A needle assembly has a needle holder (10) that holds a needle (20) and a sheath (30). The sheath has a needle compartment that accommodates the needle and any spilled drug flowing from the needle. The sheath and the needle holders are detachable. The sheath has an opening communicating with the needle compartment. A liquid barrier (LB), which can comprise a hydrophobic membrane (HM), is positioned in the first opening, blocking the first opening.  The liquid barrier allows gas to escape through the first opening but prevent liquid from leaking through the first opening during drug filling stage. In use, the sheath is positioned over the needle of a drug delivery device. The drug delivery device is filled through a separate port until its drug reservoir is completely filled, which is accomplished by filling until the drug spills out through the needle. The sheath maintains the spilled drug within the needle compartment, while air bubbles escape through the liquid barrier.

IPC: G08C17/04
Filed: 2003-02-04
Abstract: A passive inductive switch for coupling a battery to a load in a remotely deployed battery-powered electronic device. The switch operates in response to a transmitted magnetic field at a particular frequency. The switch includes an antenna for transforming the magnetic field into an induced voltage and a voltage detector for sensing the induced voltage and triggering a switching element. The switch operates in a standby mode until a sufficient voltage is induced in the antenna which causes the switch to couple the battery to the load. In the standby mode the switch draws a negligible amount of power, which permits the device to be deployed in the field for long periods of time without expending significant battery power.
